3. Cardboard Desk Pen Holder
A cardboard pen holder helps organize pens, pencils, brushes, and markers on your desk. It keeps your workspace tidy and adds a creative touch.
To make this, cut cardboard into rectangular pieces and form a box shape. You can also use empty cardboard tubes for a cylindrical design. Glue the pieces together securely and let them dry.
Once assembled, strengthen the holder by adding an extra layer of cardboard at the bottom. This prevents bending and increases durability. Paint the holder in your favorite color or wrap it with decorative paper.

This pen holder is lightweight and easy to customize. You can make multiple sections for different items. It is especially useful for students and home offices.
